Manipulation of a persistent display of shared content

ABSTRACT

The present disclosure provides a system that enables manipulation of a persistent display of shared content. Content can be shared with a host device from a guest device. A rendering of the content is configured to be manipulated by a user at the host device. For instance, a rendering of the content can be resized, scaled, rotated and moved within a graphical user interface. Annotations can also be added to the rendering of the content. The rendering of the content can also be persistently and automatically displayed in response to a device operating in a predetermined state. The predetermined state can include, for example, a lock screen mode, a bulletin board mode, or a mode when application user interfaces are minimized. The rendering may be removed from a display when the device exits the predetermined state or when the device receives a specific command to remove the rendering.

BACKGROUND

There are a number of existing software applications that enable users to manipulate the display of content on a computing device. For instance, word processing applications and presentation applications allow users to edit text and position images within a document. Such applications can also be used to add annotations to text and images. There is a wide range of applications that can be used to manipulate various types of content.

Although existing technologies allow users to manipulate the display of content, some existing systems still have a number of drawbacks. For instance, some existing systems require users to download and install specialized applications in order for users to manipulate a display of content. Such requirements can greatly hinder an adoption rate of a service utilizing the content. In addition, the requirement of an application for manipulating the display of content can increase the amount of overhead and the amount of inefficiencies of such services. The management and distribution of such applications can cause a need for a number of computing resources.

In another example, the requirement of an application for manipulating the display of content can also limit the number of ways the content can be displayed. For instance, if a user would like to display content during certain operating states of a computer, e.g., during a lock screen state, generic editing applications may not have the capability to display content, let alone allow users to manipulate the display of the content, in such operating states.

The above-described shortcomings, and other difficulties, can be exacerbated when specific applications are used to manipulate the display of content that is shared from remote computers. Such user scenarios can cause the need for specialize security measures depending permissions and privacy settings that are established for the content. This can also increase the amount of overhead and inefficiencies of services using the content, given that such services may then require resources for managing user credentials and permissions.

In view of the foregoing, it can be appreciated that there is a continual need to develop computer-implemented techniques for allowing users to manipulate the display of content without requiring specialized applications or complex systems for managing security credentials.

SUMMARY

The above deficiencies and other problems associated with existing systems are reduced or eliminated by the introduction of a system that enables manipulation of a persistent display of shared content. Content can be shared with a host device from a guest device. A rendering of the content is configured to be manipulated by a user that is physically located at the host device. For instance, a rendering of the content can be resized, scaled, rotated and moved within a graphical user interface. Annotations can also be added to the rendering of the content. The rendering of the content can also be automatically and persistently displayed when a device is operating in a predetermined mode. The predetermined mode can include, for example, a lock screen mode, a bulletin board mode, or a mode when application user interfaces are minimized or closed. The rendering may be removed from a display when the device exits the predetermined mode or when the device receives a specific command to remove the rendering.

As will be described in more detail below, the present disclosure introduces a sharing mechanism that does not rely on specific applications or credentials. The disclosed sharing systems are universally compatible with a common browser. In addition, interactions between a user and a device are improved by the introduction of a user interface that allows images and videos to be manipulated, e.g., rotated, positioned, and annotated, like virtual objects. The present disclosure also introduces a security model that is designed to prove physical access to the device. Thus, anyone that has physical access to the device can share content from their personal device, e.g., their phone. In addition, the present disclosure also enables a system to control how content is shared and displayed without requiring complex security models that require passwords and user identities.

The present disclosure also describes a system that manages interim connections for providing secure communication of content between devices. In some configurations, a server functions as a relay between a host device and a guest device. The server first determines if a person is physically present at the host device by detecting an interaction with an input device attached to the host device. In response to the input, the server generates a connection identifier that is displayed at the host device. The display of a graphical element for visually communicating the connection identifier enables the guest device to receive the connection identifier. The graphical element can be a Quick Response (QR) code, bar code, text, etc. The guest device can send a connection request to the server using the connection identifier. In response to the request, the server verifies the connection identifier and establishes a data connection between the host device and the guest device. Data can be exchanged between the host device and the guest device via the server. For instance, when the guest device sends content to the host device, the server receives the content from the guest device and relays the content to the host device. The server performs the relay of the content without storing a local copy. When the interim connection is terminated, the server restricts the connection identifier from being issued in future requests for connections with the host device.

In some embodiments, the system can also allow the guest device to share content with the host device for display on a screen of the host device. The content can be persistently displayed on a screen of the host device when the host device is in a predetermined operating mode, e.g., a lock screen or a bulletin board mode. The security models provided herein enable the content, which is also referred to herein as fridge magnets, to be securely displayed in a particular environment, e.g., postings, enterprise messages, etc.

The techniques disclosed herein provides enhanced security in a number of ways. For example, by having a server manage the interim connection, the system does not need to share network address information for a host device. In particular, a network address of the host device does not need to be shared with the user's guest device. In addition, by granting a data connection using an input that verifies that a person is physically present at the host device, the system can generate an identifier that does not require user identities and passwords. This can reduce the use of computing resources and other resources that are needed to manage those type of user credentials. In addition, since the complexities of managing credentials are not needed in the disclosed system, the disclosed techniques can also improve the usability and adoption rate of a service provided by the server and the host device. The disclosed techniques can also improve the adoption rate of a system by allowing guest devices access to a system by using generic browser applications to initiate data connections instead of complex, specialized applications.

DETAILED DESCRIPTION

FIG. 1 is a block diagram of a system 100 comprising a number of computing devices for facilitating manipulation of a persistent display of shared content. In this example, the system 100 comprises a server 101, a guest device 102, and a host device 103. The guest device 102 can comprise memory 110 including content data 111 and an application, such as a browser application 112. The host device 103 can comprise memory 110 including content data 111 that is shared by the guest device. In addition, the memory 110 comprises a data structure 170 that associates the content data 111 with a number of attributes. In some configurations, a server 101 functions as a data relay between the guest device 102 and the host device 103. As will be described below, once content data 111 is received at the host device 103, one or more input gestures can cause a manipulation of the rendering and also cause an update to the attributes according to the input gestures. The attributes can include annotation data 171, position data 172, scale data 173, an identifier 174, and one or more permissions 175. As described in the examples in FIG. 2 through FIG. 6 , different types of input gestures can be used to manipulate the rendering that is configured for persistent display during predetermined operating modes.

As shown in FIG. 2 , a system can receive a user input 201A for adding or editing an annotation associated with the rendered content 120. In this example, a user can provide an input, such as a handwriting input gesture on a touch surface, to provide an annotation to the rendered content 120. In response to this input, an annotation can be efficiently displayed on top of, or in proximity to, the rendered content 120.

In response to the input indicating an annotation associated with the rendered content 120, the host device 103 can modify the annotation data 171. The annotation data 171 can define the coordinates of the inking pattern, colors, and other display properties of an annotation provided by the user input. The annotation data 171 can be retrieved and modified according to the input gestures affecting any type of annotation associated with the rendered content 120. The modification of the annotation data 171 can be controlled by the permissions 175. The permissions, for instance, may prevent read or write access to the annotation data 171 if the device is not operating in a predetermined mode. In addition, the annotation data 171 can be accessed by the host device 103 for the display of the rendering 120 and a corresponding annotation in response to determining that the host device 103 is operating in a predetermined mode.

As shown in FIG. 3 , a system can receive a user input 201B for moving the rendered content 120. In this example, a user can provide an input, such as a dragging motion gesture on a touch surface, to cause a selection of the rendered content 120 at a first position and select a new position for the rendered content 120. In response to this input, the system can efficiently display the rendered content 120 at a new position, a function that is similar to a virtual object in a multi-dimensional environment.

In response to the input indicating a movement of the rendered content 120, the host device 103 can modify the position data 172. The position data 172 can define the coordinates of the rendered content 120, as well as a history of positions of the rendered content 120. The position data 172 can be retrieved and modified according to the input gestures affecting the position of the rendered content 120. The modification of the position data 172 can be controlled by the permissions 175. The permissions may, for instance, prevent read or write access to the position data 172 if the device is not operating in a predetermined mode. In addition, the position data 172 can be accessed by the host device 103 for the display of the rendering 120 at a location defined by the position data 172 in response to determining that the host device 103 is operating in a predetermined mode.

As shown in FIG. 4 , a system can receive a user input 201C for rotating the rendered content 120. In this example, a user can provide an input to cause a selection of the rendered content 120 at a first orientation and select a new orientation for the rendered content 120. In one example, a user input can be directed to a location at a distance from the center point of a rendering. The user can then move their pointer, or the location of their touch gesture, in a clockwise or counterclockwise direction relative to the center point. In response to this input, the system can efficiently display the rendered content 120 at a new orientation, e.g., upright or at an angle relative to a border of the user interface, a function that is similar to a virtual object in a multi-dimensional environment.

In response to the input indicating a rotation of the rendered content 120, the host device 103 can modify the position data 172. The position data 172 can define the orientation as well as the coordinates of the rendered content 120, as well as a history of the orientation of the rendered content 120. The position data 172 can be retrieved and modified according to the input gestures affecting the orientation of the rendered content 120. The modification of the position data 172 can be controlled by the permissions 175. The permissions may, for instance, prevent read or write access to the position data 172 if the device is not operating in a predetermined mode. In addition, the position data 172 can be accessed by the host device 103 for the display of the rendering 120 at a location defined by the position data 172 in response to determining that the host device 103 is operating in a predetermined mode.

As shown in FIG. 5 , a system can receive a user input 201D for scaling, e.g., resizing, the rendered content 120. In this example, a user can provide an input to cause a selection of the rendered content 120 at a first scale and select a new scale for the rendered content 120. In one example, a user input 201D can include two contact points, e.g., a two-finger input having a distance between each contact point. The user can then move the two contact points away from one another to increase the scale or move the two contact points together to decrease the scale. In response to this input, the system can efficiently display the rendered content 120 at a new scale.

In response to the input indicating a new scale of the rendered content 120, the host device 103 can modify the scale data 173. The scale data 173 can define the scale or size of the rendered content 120, as well as a history of the size of the rendered content 120. The scale data 173 can be retrieved and modified according to the input gestures affecting the scale or size of the rendered content 120. The modification of the scale data 173 can be controlled by the permissions 175. The permissions may, for instance, prevent read or write access to the scale data 173 if the device is not operating in a predetermined mode. In addition, the scale data 173 can be accessed by the host device 103 for the display of the rendering 120 at a location defined by the scale data 173 in response to determining that the host device 103 is operating in a predetermined mode.

As shown in FIG. 6 , the rendered content 120 can also include renderings of animated multi-frame images or video clips. Thus, a system can receive a user input 201E for controlling an animation of the rendered content 120. For example, a user can provide an input, such as a touch gesture on an input surface, to cause a video to playback or to pause.

The embodiments also provide combinations of operations. For instance, in a first scenario where the content data is a video clip, the system may loop the video stream in response to an input command or a determination that the device is operating in the predetermined mode. When the device is operating in a predetermined mode, video content can be automatically played. During playback, a user may provide an input gesture to move the rendering of the video. During the movement, the video playback may be paused by the device. Once the rendering is moved to a desired position, the system can allow a user to provide an input, such as a tap on a touch surface. In response, the system can resume playback of the video content.

In another illustrative example, the device can cause a rendering of a video to playback and loop at a predetermined interval. The system can receive an input to move the rendering by a drag and drop gesture. The playback can continue during the input to move the rendering and while the rendering is repositioned within a user interface. The rendering can then auto-hides after a predetermined period of time, e.g., 4 seconds.

In yet another illustrative example, the device can cause a rendering of a video to playback and loop at a predetermined interval. The system can receive an input to pause the playback of the video content. The rendering can then auto-hides after a predetermined period of time has lapsed since the input gesture.

In yet another illustrative example, the device can cause a rendering of a video to playback and loop at a predetermined interval. The system can display menu items, such as a play/pause button, and a volume control button, in response to one or more gestures, e.g., a user taps on the rendering. Based on an input to the menu items, such as a pause button, the system may pause the playback of the video content. In response, menu items, such as a play/pause button, and a volume control button, can be removed from rendering.

In some embodiments, execution of the functionality for controlling the playback of content can be allowed or restricted based on the permissions 175. The permissions may, for instance, prevent a playback or prevent a pause command from execution if the device is not operating in a predetermined mode. Thus, playback or other controls of an animation can be permitted in response to determining that the host device 103 is operating in a predetermined mode.

In some embodiments, playback of video content can be initiated when the host device determines that a person is in proximity to the host device. Thus, a host device may default to pause a video rendered on the display screen. When a person is detected to be within a predetermined distance, the system may play one or more video renderings. The host device can also select a subset of videos of a plurality of videos rendered on a display screen. The host device can then play the subset of videos in response to one or more detected events described herein. The subset may be selected based on a random selection or based on a position or arrangement of the renderings. For instance, if a number of videos are rendered, the system may only play the video renderings that are not occluded or otherwise covered by other renderings.

With reference to FIG. 7 through FIG. 12 , embodiments disclosed herein also introduce a security model that is designed to prove physical access to a device. Thus, anyone that has physical access to the device can share content from their personal device, e.g., their phone. In addition, the present disclosure also enables a system to control how content is shared and displayed without requiring complex security models that require passwords and user identities.

FIG. 7 is a block diagram of a system 100 of computing devices for facilitating interim connections using a relay server. In this example, the system 100 comprises a server 101, a guest device 102, and a host device 103. The guest device 102 can comprise memory 110 including content data 111 and an application, such as a browser application 112. In some configurations, a server 101 functions as a data relay between the guest device 102 and the host device 103. A data connection between the guest device 102 and the host device 103 can be initiated by a user interaction with the host device. This enables the system 100 to determine if a user associated with the guest device 102 is physically present at the host device 103. The system can determine if the user is physically located in proximity to the host device 103 using a number of techniques. In one illustrative example, the host device 103 can display a graphical element 161 prompting the user to provide an input directly to the host device 103. In other embodiments, the host device can also require the user to provide a voice input captured by a microphone of the host device 103 or a gesture input captured by a camera in communication with the host device. In response to the user input, the server 101 generates a connection identifier that is used to initiate a network connection between the guest device 102 and the host device 103. As described in more detail below, by the use of a relay at the server, the system to initiate and manage a bidirectional network connection without requiring the host device 103 to share network information, such as an IP address, with the guest device 102. In addition, the disclosed techniques enable the guest device to communicate data with the host device without requiring the guest device to download specialized applications.

In one illustrative example, a computer implemented method includes operations causing a display of a user interface 160 on a display screen 115 of the host device 103. The user interface 160 can include a graphical element 161 indicating the availability of functionality to receive content data 111 at the host device 103 from the guest device 102. The graphical element 161 can be configured to prompt the user for an input. For example, a user interface can have a selectable element with text “Press Here to Post Content.” The graphical element 161 can also be configured with other forms of media, e.g., other indicia or video data, indicating the availability of functionality for receiving content at the host device from a guest device. The graphical element 161 can be configured to receive the user input if the display screen 115 is a touchscreen. In some configurations, the host device 103 can also be configured to receive an input using a camera, a mouse, a keyboard, etc.

As shown in FIG. 8 , in response to a user input, the system can cause the generation of a connection identifier 202. In this example, the user input at the host device 103 causes the generation of input data 201 confirming that a user is physically present at the host device 103. The input data 201 indicating the user input can be communicated from the host device 103 to the server 101. In response, the server 101 generates the connection identifier 202. The connection identifier 202 configured to enable the server 101 to establish an interim connection between the guest device 102 and the host device 103.

As shown in FIG. 9 , the connection identifier 202 is sent from the server 101 to the host device 103. In some configurations, the connection identifier 202 is displayed in the form of a graphical element 301 on a screen 115 of the host computer 103. The graphical element 301 can be configured to visually convey the connection identifier 202 to the user. The display of a graphical element for visually communicating the connection identifier enables the guest device to receive the connection identifier by the use of a camera. The graphical element can be a Quick Response (QR) code, bar code, text, and/or a combination thereof.

The graphical element 301 can also visually communicate an encryption key. Thus, when camera of the guest device 102 is directed to the graphical element 301, the guest device 301 can obtain the connection identifier 202 and one or more encryption keys either encoded within the graphical element 301 or communicated via other methods disclosed herein. In one example, the encryption keys can be used for encrypting the content data communicated between the guest device and the host device. This can be configured such that the server 101 is not able to retrieve or interpret the communicated content data.

Although this example illustrates an embodiment where the connection identifier 202 is displayed in the graphical element 301, the connection identifier 202 can be communicated to the guest device 102 using other techniques. For instance, the guest device 103 can generate an audio signal and an audible output for communicating the connection identifier 202 to the host device 103. Thus, a guest device 102 that is in proximity to the host device 103 can readily capture the audible output using a microphone, and the audible output can communicate the connection identifier 202. In another embodiment, the host device 103 can generate other types of signals that communicate the connection identifier 202, e.g., light or other modulated signals for communicating the connection identifier 202 from the host device 103 to the guest device 102.

As shown in FIG. 10 , the guest device 102 can obtain the connection identifier 202 and use the connection identifier 202 to establish the interim connection 510 with the server 101. In one illustrative example, the guest device 102 can capture the connection identifier 202 by the use of a camera that is directed to the graphical element 301 displayed by the host computer 103. Although this example utilizes a graphical element for communicating the connection identifier, the guest device can obtain the connection identifier from the host device using any suitable communication means such as, but not limited to, an audible sound generated by the host device and captured by a speaker of the guest device, a light signal generated by the host device and captured by a sensor of the guest device, or by the use of any other communication protocol, e.g., NFC, Bluetooth, Wi-Fi, etc.

Once the guest device 102 obtains the connection identifier 202, the guest device 102 can send a confirmation input 501 that includes the connection identifier 202 to the server 101. The confirmation input 501 then causes the server 101 to establish the interim connection 510 between the guest computer 102 and the host computer 103 through the server 101. In some embodiments, the interim connection 510 can comprise two components, a first connection between the server 101 and the host device 103, and a second connection between the server 101 and guest device 102. The first connection and the second connection can be established and maintained independently. The first connection can be established before the second connection is established. For example, the first connection can be established when the host device 103 receives the user input and requests to communicate the input data 201. The second connection can be established in response to the confirmation input 501.

The confirmation input 501 can be generated by a generic application, such as the browser application 112. Thus, in some embodiments, other metadata can be communicated to the guest device 102 along with the communication of the connection identifier 202. In one illustrative example, the graphical element 301 on a screen 115 of the host computer 103 can also include data defining a URL. The URL can include the address of the server 101. Thus, when the guest device 102 captures the data embedded in the graphical element 301, the guest device 102 can utilize an application, such as the browser application 112, to send the confirmation input 501 including the connection identifier 202 to the server 101.

When the guest device sends the confirmation input 501, e.g., a connection request, to the server using the connection identifier, the server can verify the connection identifier with a data store of valid connection identifiers. As shown in FIG. 11 , once the server 101 verifies that the connection identifier 202 is valid, the server establishes a data connection, e.g., the interim connection 510, between the host device 103 and the guest device 102. Data, such as the content data 111, can be exchanged between the host device and the guest device via the server. For instance, when the guest device transmits content data, the server receives the content data from the guest device and relays the content to the host device. The server performs the relay of the content without storing a local copy. Thus, the interim connection 510 can enable secure delivery of the content data 111 from the guest computer 102 to the host computer 103.

As shown in FIG. 12 , the server 101 can terminate the interim connection 510 in response to a detection of one or more events at the server 101. The one or more events can include, but are not limited to, a user input at the guest device 102 requesting termination of the connection, a timeout event that is invoked after a predetermined period of time has elapsed after a data rate between the devices has dropped below a threshold, or a completion of a data transfer. When the interim connection 510 is terminated, the server 101 regulates the use of the connection identifier 202 associated with the interim connection 510. Thus, subsequent processes for generating prevent or reduce occurrences where one or more new connection identifiers are identical to the connection identifier 202.

FIG. 13 is a flow diagram illustrating aspects of a routine 700 for enabling aspects of the present disclosure. It should be appreciated that the logical operations described herein with regard to FIG. 13 , and the other figures, can be implemented (1) as a sequence of computer implemented acts or program modules running on a computing device and/or (2) as interconnected machine logic circuits or circuit modules within a computing device.

The particular implementation of the technologies disclosed herein is a matter of choice dependent on the performance and other requirements of the computing device. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These states, operations, structural devices, acts and modules can be implemented in hardware, software, firmware, in special-purpose digital logic, and any combination thereof. It should be appreciated that more or fewer operations can be performed than shown in the figures and described herein. These operations can also be performed in a different order than those described herein.

It also should be understood that the illustrated methods can end at any time and need not be performed in their entireties. Some or all operations of the methods, and/or substantially equivalent operations, can be performed by execution of computer-readable instructions included on a computer-storage media, as defined below. The term “computer-readable instructions,” and variants thereof, as used in the description and claims, is used expansively herein to include routines, applications, application modules, program modules, programs, components, data structures, algorithms, and the like. Computer-readable instructions can be implemented on various system configurations, including single-processor or multiprocessor systems, minicomputers, mainframe computers, personal computers, hand-held computing devices, microprocessor-based, programmable consumer electronics, combinations thereof, and the like.

For example, the operations of the routine 700 can be implemented by dynamically linked libraries (“DLLs”), statically linked libraries, functionality produced by an application programming interface (“API”), a compiled program, an interpreted program, a script, a network service or site, or any other executable set of instructions. Data can be stored in a data structure in one or more memory components. Data can be retrieved from the data structure by addressing links or references to the data structure.

Although the following illustration refers to the components of the figures, it can be appreciated that the operations of the routine 700 may be also implemented in many other ways. For example, the routine 700 may be implemented, at least in part, by a processor of another remote computer, processor or circuit. In addition, one or more of the operations of the routine 700 may alternatively or additionally be implemented, at least in part, by a chipset working alone or in conjunction with other software modules. In the example described below, one or more modules of a computing system can receive and/or process the data disclosed herein. Any service, circuit or application suitable for providing the techniques disclosed herein can be used in operations described herein.

The routine 700 begins at operation 701 where a computing device, such as the host device 103, receives a user input at an input device and generates input data 201 confirming an interaction between a user and the host computer 103. As shown in FIG. 8 , input data 201 can be generated in response to user input received at an input device 115 that is physically located at a location of the host device 103. The input data can be communicated from the host device to the server. In operation 701, the host device 103 can initiate a first connection with the server for communicating the input data. This first connection can be maintained and utilized throughout the operations of routine 700, including the operations for facilitating and managing the interim connection with the guest device 102.

In some configurations, operation 701 can involve a process where the system verifies that an input was provided by a user located at the host computer. For instance, during an initialization process, the server 101 can receive hardware data identifying an input device such as a keyboard or touchpad type, e.g., a model number or serial number. The input device can be associated with a hardware identifier indicating the device type. This information can be communicated to the server when a host device 103 is in a registration process with the server. This registration process can occur before operation 701, e.g., the hardware data is communicated to, and stored at, the server prior to the display of the user interface and the prompt for a user input.

Thus, when the user input occurs, the host device 103 can send the hardware data to the server for confirming that the user input was generated by the same input device registered in memory. By enabling the server 101 to verify that a hardware identifier stored at the server matches the hardware identifier sent in conjunction with the input data, the system can avoid tactics where a user sends false input data in an effort to appear that they are physically located at the host device.

Next, at operation 703 and shown in FIG. 9 , the connection identifier 202 can be generated in response to receiving the input data at the server 101. The connection identifier 202 is configured to establish the interim connection between the guest device 102 and the host computer 103 through the server 101. As described herein, and shown in FIG. 9 , the connection identifier 202 can be generated at the server 101 in response to a user input received at the host device 103.

Next, at operation 705, the system can cause display of a graphical element 301 that is configured to visually convey the connection identifier 202 in the display of the graphical element 301. The graphical element 301 can also communicate other data, such as an encryption key. The graphical element 301 is configured for visually conveying the connection identifier 202. The graphical element 301 can be, for instance, a QR code. The graphical element can also indicate a URL for the server. This display enables the communication of connection identifier 202 and any network address data of the server to the guest device 102. Once the guest device obtains the connection identifier and the URL, the guest device can send a confirmation input 501 to the server. The confirmation input can be delivered by a guest device 102 and sent to the server 101 using the address information, e.g., a URL, provided by the host device.

Next, at operation 707, and as shown in FIG. 10 , receipt of the confirmation input at the server causes the server to establish a network connection, e.g., the interim connection, with the guest device. The server can then use the existing connection with the host device to relay content data from the guest device to the host device. In some configurations, the interim connection can include a first connection between the guest computer and the server and a second connection between the host computer and the server, wherein the secure delivery of the content data from the guest computer to the host computer comprises communicating the content data from the guest computer to the server. The server relays the content data to the host computer in response to receiving the content data at the server, the server configured to restrict storage of the content data on a storage device controlled by the server. In some embodiments, the server can only handle the data in parts. Thus, if the server never sees all of the content data at one time, this may help preserve privacy.

Next, at operation 709, once the content is communicated between the guest device and the host device, the host device can display a rendering of the content data received from the guest device. In some configurations, the display of content is persistent when the computer is in predetermined modes, e.g., screen lock, a bulletin board mode, surface hub mode, etc. For instance, the rendering of the content data can be automatically displayed in response to detecting that the host computer is in a predetermined mode, wherein the predetermined mode comprises a lock screen mode, a bulletin board mode, or when the device closes one or more applications. The rendering of the content data can be persistently displayed while the device is in the predetermined mode or until the computing device receives a command to remove the rendering of the content data.

Next, at operation 711, the host device can receive input data to modify the rendering of the content data. A variety of input gestures, e.g., digital ink input, voice input, or a gesture input, can be used to modify one or more display properties of rendered content. For example, any suitable input can cause an image rendering to be rotated, positioned, or annotated, like virtual object. The object can be left on the display while the host device is operating in a predetermined mode. In some configurations, any user that is physically present at the host device can cause further manipulation to the rendering with an input gesture. Such configurations can allow the rendering to function as a bulletin board posting or a refrigerator magnet. Any user can remove the posting, resize the posting, reposition the posting, etc.

In some configurations, operation 711 can configure the permissions, where the permissions cause the rendering 120 of the content 111 to be automatically displayed using the one or more attributes when the computing device is in a predetermined state. In some configurations, the predetermined state may include a state where the host device is running less than a threshold number of applications in a foreground process, e.g., applications that are displaying a user interface on a device desktop. In some configurations, the predetermined state may include a state where the host device is in a Hub mode, a multi-user or open user mode where people can interact with a touch screen to modify content, like a bulletin board or refrigerator with modifiable magnets. In some configurations, the predetermined state may include a state where the host device is in a lock screen mode, where a password is needed to enter full functionality of an operating system but configured to allow users to manipulate and remove a select set of shared content 111.

In some configurations, operation 711 can configure the permissions to cause the rendering 120 of the content 111 to be automatically displayed using the one or more attributes when the computing device is in a predetermined state. The permissions can also be configured to permit a new user input to modify the rendering 120 of the content 111 and at least one attribute associated with the content 111 while the computing device 103 is in the predetermined state. The predetermined state can include an ambient state where no applications are running in as a foreground process and/or displaying a user interface. The permissions can also be configured to cause the display of the rendering 120 of the content 111 to be removed when the computer exits the predetermined state. For example, the rendering 120 of the content 111 can be removed from display when a user opens an application or brings a background process to a foreground process and opens a user interface corresponding to the application running as a foreground process.

At operation 713, as shown in FIG. 12 , the server can terminate the interim connection 510 in response to a detection of one or more events at the server 101. The interim connection can be terminated in a number of different ways. For instance, a connection can be terminated manually, e.g., a user input at any device, upon completion of transferred content, or after a timeout period. In some embodiments, the one or more events causing the termination of the interim connection can include at least one of receiving a supplemental input from the guest computer requesting termination of the interim connection, determining that the interim connection has not been used for a predetermined time period, or determining that a predetermined amount of data has been communicate over the interim connection.

In some configurations, operation 713 may involve a process where the connection between the server and the guest device, or the connection between the host device and the guest device, is terminated in response to a detection that the user of the guest device and/or the guest devices is no longer in proximity to the host device. The host device can be in communication with a camera or a proximity sensor (such as a infrared sensor or a doppler sensor). The host device can be in communication with a radio device signal enabling the host device to determine when the guest device is within a predetermined distance to the host device. The sensor or the radio of the host device can provide a signal enabling the host device to determine when the user of the guest device, or when the guest device, is no longer in proximity to the host device, e.g., within a threshold distance to the host device, and in response terminate one or more connections described herein.

In such embodiments, before a connection to the guest device is established, the host device may also require that the person and/or the guest device is in proximity, e.g., when the guest device is within a threshold distance to the host device. Thus, before server and/or the host device makes a connection to the guest device, the host device may not allow the guest device to connect with the server and/or allow the guest device to connect with the host device if a sensor or radio of the host device detect that a user and/or the guest device is not in proximity to the host device. In other words, the host device may not allow the guest device to connect with the server and/or allow the guest device to connect with the host device if the host device determines that user and/or the guest device is outside a predetermined distance to the host device.

In some configurations, operation 713 may involve a process where the connection between the server and the guest device are terminated while the connection between the server and the host device are preserved. This enables the host device to communicate information with the server once the connection with the guest device is terminated. Termination of the connection between the server and the host device can be initiated by the host device or the server independently.

At operation 713 or in other operations of the routine, the server 101 can also regulate subsequent processes for generating new connection identifiers. In some embodiments, the server can control the subsequent processes to prevent or reduce occurrences where any newly generated connection identifiers are identical to the connection identifier 202. Thus, re-use of any connection identifier can be eliminated or delayed for a predetermined period of time.
